WIN `DOIN-SASH SUPPORT.

Application led September 7, 1926. Serial No. 133,925.

Vend thereof.

Inv a prior application, No. 120,599, led July 6th, 1926, a window of the swinging type was shown and described. The improvement in the present invention over that shown in my prior application resides in the manner in which the upper sash is supported in a piv-V otal manner so that the upper end of the sash may be swung inwardly and to prevent either lateral or vertical play of the sash while it is being moved.

It is desired to so support and pivot the upper sash that it may be swung inwardly with no liability of the sash becoming detached accidentally during the swinging movement and thus endangering the operator.

Referring to the drawing herewith, Fig. 1 is a side elevation of the upper and lower sash, showing the support for the upper sash. Fig. 2 is a similar view illustrating a different position of the Vsashes relative to each other. Fig. 3 is a detached view of the upper sash in reversed position. Fig. t illustrates the joint between the upper and lower sash taken approximately on the line 1 -4f of Fig. 5. Fig. 4 is a section through the supporting plates illustrating a slightly diiierent embodiment of the supporting connection from thatv illustrated in Fig. 4. Fig. 5 is a section showing the mounting of the upper sash. Like numerals of reference are employed to designate like parts in all the views.

In the type of window to which my invention is applied the lower sash 1 1s adapted to be raised upwardly in a channel in the casing in the manner usual in most types of windows. The upper sash 2, however, is not adapted to be moved longitudinally in the casing, but is supported in such manner that the upper end may be swung inwardly to provide a vent at the upper end or to entirely reverse so that access may be had to the outer4 face of the window pane that the same may be cleaned.

The manner in which theupper sash is supported for this purpose constitutes the subject matter of the invention.

The lower sash 1 is provided adjacent its upper end with laterally projecting pins 3 to tit Within a. slot 15 in a rider 16. To the rear of the upper end of the lower sash 1, attached to the casing 4, is a supporting plate 5. Said plate constitutes a strip of metal, the upper side 6 of which is horizontally arranged to support the upper sash. The forward end of the plate is formed into a bracket 7, the upper face ot which is increased in width as shown at 8 in Fig. 1-, the two sides being spaced apart to torm a groove 9 between them, said groove being arcuate to allow rotative movement of the sash support therein.

The upper sash 2 has adjacent its lower end a plate 10, said plate having an arm 11 pro- ]ectlng therefrom, the lower side of the plate and arm forming a horizontal face 12 adapted to rest upon the upper face 6 of the supporting plate. The forward end of the arm 11 has a downwardly curved hinge member 13 thereon of suiiticientlwidth to lit between the walls of the groove 9 and curved to fit the arcuate shape ot the groove.. On the upper side of the curved member a slot or recess 14 is tormed to receive the pin 3 upon the lower sas i.

When the upper sash is in erect position, as

shown in Fig. 1, the lower sash and the pins 3 thereon will be allowed to move upwardly when the sash is raised, as shown in dotted lines in Fig. 1. The upper sash will be supported by the contact of the plates 10 with the supporting plates 6 on the casing.

When it is desired to swing the upper end or" the sash 2 inwardly the lower sash will be moved to its lowermost position, bringing the pin 3 within the recess 14 in the arm 11. The upper end of the sash may be then swung inwardly and in so doing the pin 3 will form a pivot for the sash. The lower side of the curved member 13 will rest within the groove 9 and it will be obvious that there will be no play or lost motion in the hinge formed by the arrangement described. The sash cannot be drawn upwardly because of its contact with the pin 3. It may not be moved downwardly or laterally due to the close Contact of the curved member 13 with the wall of the groove 9. Vhen the sash has been entirely reversed to the position shown in Fig. 3, however, it may be raised directly upward and removed from the casing.

I have shown the plate 11 on the upper sash as fitting within a groove 9 in the supporting bracket 7 In Fig. 4a I have shown the plate 11:L as formed with a groove 9a on its lower side, and the supporting plate 5 has its forward end 7 shaped to iit within the groove 9.

This, as will be noted, is practically a reversal of the parts as shown in Fig. 4. ylhe action, however, will be the same in all respects.

The advantages of this construction lie in the positive engagement of the pivotal 'portion, connection and support of the upper sash. It may be moved easily to swing the upper end inwardly, and when this swinging movement is performed there can be. no accidental release of the upper sash until it is entirely reversed in position, and in that position the sash will be supported upon the pin 3 through the force of gravity. rlhe further advantages of this construction will be apparent to those skilled in the art.

What I claim as new and desire to protect by Letters Patent is:

l. Awindow including a lower sash adapt ed tol slide vertically upward, laterally projecting pins adjacent the upper end thereof, an upper sash, a plate at each side of said upper sash adjacent the lower end thereof, a. forwardly extending arm on each of said plates, said arms having slots therein engaging said pins and a stationary bracket below said plate and arm, said bracket having a groove therein to receive said extension the sides of said groove serving to limit the lateral movement of said extension for the purpose described.

2. A window including a casing, upper and lower sash, said lower sash having laterally extending pins thereon, an upper sash, plates at the lower end thereof within said casing and engaging said pins, supporting brackets on said casing to receive said plates, an arcuate groove in the forward end'of each of said brackets and curved ends on said plates fitting within said grooves to permit said upper sash to swing on said brackets.

3. A window including a casing, upper and lower' sash, said lower sash having laterally extending pins thereon, an upper sash, plates at the lower end thereof, supporting brackets on said casing to receive said plates, an arcuate groove in the forward end of each of said brackets and curved ends on said plates tting within said grooves, said curved ends having slots engaging about said pins.

4. In a window, a casing, a sash therein, a forwardly-extending plate on said sash between said sash and casing, an arcuate hooked` arm on said plate, a bracket below said plate on said casing, said bracket having anupper groove to receive said arm to allow a turning movement of said arrn in said groove when -saidsash is swung forwardly.

5. In a window, a casing, a sash therein, a flat plate at each side of said sash between said sash and said casing, Hat brackets on said casing in the planes of said plates and acting to support said plates and sash, said plates and brackets formed to allow said plates to pivot on said brackets, and interfitting means on said brackets and plates to prevent lateral play of said plates on said brackets during swingingl of said sash.

ln testimony whereof l hereunto aiixY my signature this 30 day of August, A. D. 1926.
